I have a unique combination of talents. I am a writer. I have also been a mystery shopper for over 10 years, and have designed and maintained my own personal site from scratch for 15+. A mystery shopper visits businesses from the prospective of the average shopper and gives feedback back to the business owner. I write a lot of website content, but I also have the skill set to evaluate not just your content, but it's navigability and overall appeal to the average visitor.
I will critique your site from the viewpoint of your average visitor and give you feedback which can help you make improvements.
